Java 9 support remains in beta stage, because Java 9 itself will not be made available until Java Development Kit 9 ships on September 21. Oxygen’s Java 9 support includes the ability to add the Java Runtime Environment for Java 9 as the installed JRE as well as backing for the Java 9 execution environment. Developers also can create Java and plug-in projects using Java 9 and compile modules that are part of a Java project. Eclipse’s signature Java IDE has been enhanced as well, with improvements to the UI.

Focused on open source tools, Eclipse has offered annual release trains every June since 2006, letting developers coordinate upgrades or new releases of multiple projects. Last year’s release train, Neon, offered tools for Docker and JavaScript. June 2018’s release is slated to be called Photon.
